Definitions

  • the invention relates to an apparatus for driving upper and lower tool parts for punching, cutting and stamping, and more particular to such an apparatus using not a piston-cylinder device but a rotary screw rod and a nut member threadedly engaging with the screw rod so as to move up or down therealong.
  • the upper and lower tool parts are symmetrically moved toward or apart with each other always at a same rate.
  • Those skilled in the art may understand that it is necessary or preferable to drive the two tool parts asymmetrically so to speak in such engineering work. For instance, one part only is moved while the other is stopped, one part is slowly moved but the other is rapidly moved, or the two parts are time-differentially moved.
  • the object can be attained fundamentally by using a ball screw rod pair comprising a first ball screw rod having an unthreaded extension and a hollow second ball screw rod embracing the unthreaded extension so as to allow relative rotation and a pair of prime movers, e.g. servomotors through a pair of transmitting systems for separately rotating said first and second screw rods.
  • a ball screw rod pair comprising a first ball screw rod having an unthreaded extension and a hollow second ball screw rod embracing the unthreaded extension so as to allow relative rotation and a pair of prime movers, e.g. servomotors through a pair of transmitting systems for separately rotating said first and second screw rods.
  • a base bed 1 as a part of the machine casing MC supports four first ball screw rods 11 (arranged at four corners of the machine casing MC, see Fig. 2).
  • each of the ball screw rods 11 is supported at the lower end by a bearing 2 for rotation, which is mounted around the periphery of a groove 3 formed in the base bed 1.
  • a first table 13 is fixed to the four nut members 12 so that a lower or first tool part (not shown) may be removably or exchangeably mounted thereon.
  • a hollow second screw rod 21 is supported by an upper tapered bearing 22, which is fixed to a crown member 4 as a part of the machine casing MC via a flanged ring 23, and embraces an unthreaded extension 11' of the first screw rod 11 so as to relatively rotate with each other.
  • a needle bearing 24 is preferably arranged at the lower end of the second screw rod 21 between the inner peripheral surface thereof and the outer peripheral surface of the first screw rod extension 11'.
  • a second nut member 25 is threadedly engaged with the second screw rod 21 so as to move up or down when the rod 21 is rotated in one or other direction by means of a second reversible servomotor SM2. This is applied also to the other three screw rods 21.
  • a second table 26 is fixed to the four nut members 25 so that a second or upper tool part (not shown) may be removably or exchangeably mounted thereunder.
  • thread cutting direction of the second screw rod 21 is made opposite to that of the first screw rod 11 so that when the second table 26 is lowered by rotation of the former screw rod then the first table 14 may be raised by rotation of the latter to be appreciated when force transmitting mechanism is explained later in reference to Fig. 5 and Fig. 6.
  • the unthreaded extension 11' of the first screw rod 11 is provided at the upper end with a first belt pulley 15 and the second screw rod 21 is provided with a second belt pulley 28 thereunder in concentricity therewith for the purpose of drivingly rotating them.
  • pulleys 15, 28 of the two screw rods 11 (21), 11(21)shown above in Fig. 2 are arranged at a level a little higher than those shown below as seen from comparing the left pulleys 15, 28 with those shown at the right, by reason to be made clear when explaining Figs. 5 and 6.
  • the reversible servomotors SM1 (Fig. 5) and SM2 (Fig. 6) which are numerically controlled by a computer (not shown), are respectively mounted on a plate 5 which is fixed to the crown member 4 so as to protrude the respective motor shafts downward, on which belt pulleys 31 and 41 are respectively mounted.
  • first and second cylindrical transmission casings 51 (Fig. 5) and 61 (Fig. 6), each of which has a rod 52 and 62 respectively for rotating therein.
  • the rotatory rods 52, 62 are respectively connected at the lower end with free wheeling clutches for the purpose to be explained later.
  • the free wheeling clutch CL2 for the rod 62 is shown in Fig. 6.
  • the free wheeling clutch for the rod 52 is the just same with the clutch CL2 and connected thereto likewise.
  • the rod 51 is mounted at the upper portion protruded out of the casing 51 with a pulley 32 at a level same with the pulley 31 on the motor shaft so that a timing belt TB1 is extended therearound for rotating the rod 52 in either direction by the reversible motor SM.
  • the rotating rod 51 is provided with a further pulley 33 above the pulley 32 so that a timing belt TB2 is extended around the pulley 33 and the upper pulleys 15, 15 of the two screw rods 11, 11 shown above in Fig. 2 via a guide roller GR1 so as to drive these two screw rods 11, 11 for rotation.
  • the rotating rod 51 is provided with a still further pulley 34 above the pulley 33 so that a timing belt TB3 is extended around the pulley 34 and the upper two pulleys 15, 15 mounted at a level higher than the above two pulleys on the first screw rods 11, 11 shown below in Fig. 2 via a guide roller GR2 so as to drive these two screw rods 11, 11 for rotaion.
  • a pulley 41 is mounted on an output shaft of the SM2.
  • a rotary rod 62 is similarly mounted in a transmission casing 61 and provided with a pulley 42 so that a timing belt TB4 is extended around this pulley 42 and the motor shaft pulley 41 so as to drive the rod 62 for rotation.
  • the rod 62 is mounted with a further pulley 43 below the above pulley 42 and a still further pulley 44 below the further pulley 43.
  • a timing belt TB5 is similarly extended around the further pulley 43 and the pulleys 28, 28 of the second screw rods 21, 21 shown above in Fig. 2 via a guide roller GR3 for rotating these hollow screw rods.
  • a timing belt TB6 is similarly extended around the still further pulley 44 and the pulleys 28, 28 of the two second screw rods 21, 21 shown below in Fig. 2 via a guide roller GR4 for rotating these hollow screw rods.
  • the servomotors SM1, SM2 are energized to rotate respectively in one direction, the lower tool part and the upper tool part are respectively moved toward each other for engagement, while when rotating in the other direction the both tables 13, 26 are moved for disengagement so as to take out the tooled product and supply new material to be tooled therebetween. Since there are provided the two motors SM1, SM2 for driving the upper and lower tables 13, 26 independently, the tools respectively fixed thereto may be asyndrically moved up and down as occasion demands.
